Today Katrina gave me a fortune about the police station and said something about a tshirt being the key to my good fortune. What does it all mean? I really want the police station and i think this might make it so i can get it.

Villagers request for you to build the police station, not special visitors. If she mentioned a specific t shirt, wear it, as it will make you lucky all day and reverse any negative effects (less likely to find bees) and less tripping, etc etc

Both my characters were told by Katrina to wear pants. One of them went to the island at 3 PM, wearing pants, and *majorly* scored, earning about twice the bells that I would usually get at that time. Katrina's fortunes might actually be worthwhile!
